Answer:
a. water into root hair cells
Explanation:
Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a semi-permeable from a region of high concentration to a region of lower concentration.
Hence, the process of osmosis is best illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.
Answer:
B. Glucagon
Explanation:
Glucagon is a pancreatic hormone, secreted by the alpha cells of islets of Langerhans. Whenever the blood glucose level falls, glucagon is released to increase the blood glucose levels. This function of glucagon is quite opposite to the function of insulin and hence both are antagonistic hormones. Insulin reduces the blood glucose where as glucagon increases the blood glucose.
Glucoagon is large polypeptide of 29 amino acids. Since it helps in increasing the blood glucose homeostatic levels it is called as hyperglycemic hormone. It does so by stimulating certain processes such as:
- Stimulating Glycogenolysis i.e breakdown of glycogen to release more glucose from liver.
- Stimulating Gluconeogenesis i.e. synthesis of glucose from non-carbohydrate sources like proteins.
- Glucagon inhibits the process of glycogenesis i.e. synthesis of glycogen, the storage form of glucose.
Hello, 3Coli here!
Here is your answer:
My data supports the hypothesis as supporting evidence. My hypothesis would not have existed if I didn't have evidence. If a hypothesis doesn't match my data, it could be wrong.
Hope this helps! :D

Answer:
The tail of the sperm, the flagellum
Explanation:
We find cilia in the human body. They coat the epithelial cells of the upper respiratory tract and play a role in keeping dust particles, smog, and potentially harmful microorganisms from entering the lungs.
Their movements enable the movement of mucus or other substances across the surface of various epithelial cells. The cilia also cover parts of the male and female reproductive tract.
Flagella are found in sperm, whose tail represents the flagellum in its structure. The body wall of the sponge, among others, contains cells with whips that create and maintain the flow of water through the body.
